A dermatologist has explained how to get rid of the rough, bumpy skin some people have on the tops of their arms.
Dr Chris Tomassian, a dermatologist who posts on his @drtomassian TikTok account, responded to a clip about the 'weird, arm bumps' to say it's something called keratosis pilaris and is 'super common and not harmful'.
He suggests anyone with the condition use a lactic acid solution twice a day or a salicylic acid lotion. Before adding: "Be consistent, use them daily and avoid dry skin."
In the comments section, the doctor explained it's 'basically retained skin cells in the hair follicle'.
TikTok users replied to the clip thanking Dr Tomassian for the advice, with one person writing: "OMG thank you so much! I have had these for so long."
Another wrote: "So this is what my son has - I thought it was an allergic reaction."
A third posted: "I've had this since I was 14, I never knew why. This is so helpful."
As well as the arms, the bumps also commonly appear on the things and bottom, but can pop up in other areas, too.
They're usually red, white, skin-toned or darker than your skin and can feel itchy.
According to the NHS, the condition is caused when your hair follicles become blocked with a built-up of keratin - a substance found in your skin, hair and nails.
It's not contagious and no one knows why it happens, but it can run in families so there's a good chance if one of your parents has it, then you might end up with it too.
The NHS also explains that most people who do have keratosis pilaris 'have it for years' but say it can clear up by itself.
Much like Dr Tomassian, the NHS suggests moisturising your skin, and say you can ask a pharmacist for help on what's most suitable.
The NHS also recommends using mild and unperfumed soap and other bathing products, as well as having lukewarm baths and showers instead of hot ones.
An exfoliating mitt or washcloth can be used to gently scrub the skin, and once you're out of the bath or shower pat your skin dry rather than rubbing it.
It should go without saying, but don't pick at or scratch the bumps, avoid harsh scrubs and any products that might dry out your skin.
